Black lines after unlocking

[Krissg1151]

I have a Samsung S20 FE 4g

I have noticed since the newest android 12 updates when the unlock s reen is transitioning to the home screen I have black verticle lines that will appear for a split second, it only happens during this transition though, this never happened with the older OS.

Does anyone have any ideas how I can remedy this?

Thanks in advance.

Hello, what is the update in your phone? Did the lcd changed?

Yes after i update. 

Just tell to service center to change lcd . They changed my lcd a week from now and i still not see this black vertical.lines when unlocking. 

Tips before you surrender your phone to service center just check your phone that no have dent scratch just like or just take video of your phone. 

Because i just experience that my A55 5g they return my phone have dent on the side . And i protest it to them so i think that the reason why they changed my lcd.
